The Cisco ® Route Processor Module (RPM-PR) is an integrated IP/Multiprotocol Label Switching (MPLS) service route processing module for the carrier class Cisco MGX ® 8880 Media Gateway and Cisco MGX 8950/88x0 family of Advanced ATM Multiservice Switches.
The Cisco RPM-PR based on the NPE-400 processor allows service providers to quickly enable new, high-margin IP services using Cisco IOS ® Software. The Cisco RPM-PR provides high-quality, scalable, IP and ATM integration using MPLS technology to create scalable Internet solutions.
The Cisco RPM-PR enables the switch to provide integrated IP/MPLS-based VPN and quality-of-service (QoS) services along with ATM and other multiservice capabilities using Cisco IOS ® Software. The Cisco RPM-PR can expand the switch's capabilities to offer Layer 3 services and enable migration from Layer 2 to Layer 3 networks. The Cisco RPM-PR is used by Cable, Wireline, and Wireless service providers as well as enterprise customers.


• IP/MPLS-enabled multiservice networks for service provider and enterprise networks

• Differentiated IP Radio Access Network (IPRAN) voice and data service aggregation using MLPPP and PPPMUX protocols

• Support for IPv4 Multicast and Multicast VPN

• Bandwidth savings through Routing Table Protocol (RTP) header compression for IP services

• Highly secure RTP stream transport with IPSec

• Voice-over-IP (VoIP) services with no service interruption due to failure

• New IP Next-Generation Network converged wireline and wireless services

Product Specifications

The Cisco RPM-PR is a hot-swappable full-height card for the Cisco MGX 8830, MGX 8850, MGX 8880, and MGX 8950 switches. The Cisco RPM-PR supports the following half-height backcards:

• Half-height four-port Ethernet (10BASE-T)

• Half-height one-port Fast Ethernet (full duplex)

• Half-height one-port Fast Ethernet (full duplex) along with accelerated cRTP

• Half-height five-port auto sensing to Ethernet, Fast Ethernet, or Gigabit Ethernet speed

Note that I/F speed and effective throughput is determined by the performance of the packet processing engine in the RPM-PR.
The Cisco RPM-PR along with Cisco IOS Software offers network intelligence for business-critical solutions. The following tables provide product highlights addressing:
